辽宁某金矿矿石中主要金属矿物为磁黄铁矿和毒砂,脉石矿物主要为石英、绢云母、绿泥石、碳酸盐等。金银矿物为自然金、银金矿、金银矿、自然银。矿石中主要可回收元素为金、银,主要杂质元素为砷。试验进行单一浮选流程及重选-重选尾再磨浮选流程试验,结果表明,在重选磨矿细度-0.074 mm含量69.3%时,获得重选精矿金品位59.7 g/t,重选回收率46.03%;在重选尾再磨细度-0.074 mm含量88.5%时,获得浮选精矿金品位19.3 g/t,浮选回收率38.16%,重浮总精矿金品位30.48 g/t,金总回收率84.19%。
The main metallic minerals in a gold mine in Liaoning Province are pyrrhotite and arsenopyrite. The gangue minerals are mainly quartz, sericite, chlorite and carbonate. Gold and silver minerals for the natural gold, silver and gold, gold and silver mines, natural silver. The main recoverable elements in the ore are gold and silver, and the main impurity element is arsenic. The experiment carried out a single flotation process and the re-election tail-refurbishment flotation flow test, the results show that in the re-election grinding fineness of -0.074 mm content of 69.3%, the re-election concentrate gold grade 59.7 g / t, Re-election recovery rate of 46.03%; re-election tail refinishing fineness of -0.074 mm content of 88.5%, the flotation concentrate gold grade 19.3 g / t, flotation recovery rate of 38.16%, heavy gold concentrate grade 30.48 g / t, the total gold recovery rate of 84.19%.
